If you find that a product that you need is not available in the Manufacturer Libraries please inform Stardraw.com by making a Symbol Request. Requests made by users of Stardraw Design 7 are the basis by which additions to the libraries are prioritized and the only way we can know which products you need to have added (we can't guess!).
On the Symbol Request page, click on the manufacturer you want (or, if the manufacturer is not listed, click on the link to "Add a New Manufacturer" at the bottom of the page), and if the product you want is not listed click on the link to "Add a New Product Request".
